Why could the mass of argon be greater than the mass of potassium even though it has a lower atomic number?

1 answer:

6 0

The mass given on the periodic table is the weighted average of the abundance of isotopes. Because heavier isotopes (more neutrons) of argon are more abundant than potassium's, by pure statistics, argon will appear with a greater mass on the periodic table.

in easy way

we can also say :- Argon has greater proportions of heavier isotopes with more neutrons than potassium.

Four springs are stretched to the same distance from the equilibrium position. The spring constants are listed in the table. A 2

svp [43]

Answer:

The correct option is;

X, W, Y, Z

Explanation:

The parameters given are;

Spring (S), Spring Constant (N/m)

W, 24

X, 35

Y, 22

Z, 15

The equation for elastic potential energy, $E_e$ , is $E_e = 0.5 \times k \times x^2$

The above equation can also be written as $E_e =\dfrac{1}{2} \times k \times x^2$

Where:

k = The spring constant in (N/m)

x = The spring extension

Therefore, since the elastic potential energy, $E_e$ , of the spring is directly proportional to the spring constant, k, we have the springs with higher spring constant will have higher elastic potential energy, $E_e$ , therefore the correct order is as follows;

X > W > Y > Z
